Embodiment Construction

[0022] 1. Preparation of nanoparticle powder:

[0023] Hydrolyze borate and deionized water in a high-speed stirring mixer, add sodium nitride respectively after the borate is completely dissolved; hydrazine hydrate; slowly heat up and continue stirring until completely dissolved, add coupling agent and ethanol; Add ammonium molybdate when the solution is transparent; control the addition of copper sulfate after the solution is stable; form boron, molybdenum, and copper under the catalysis of boron, molybdenum, and copper with covalent and coordination bonds. The material components used are calculated based on the components of the product; the sol is pumped into the high-pressure reactor, and the air in the high-pressure reactor is exhausted with nitrogen. After the tank is sealed, it is heated slowly, and samples are taken regularly to observe the shrinkage and aging of the gel volume. until the double salt crystal nucleus gel is aged and formed in the high-pressure reactor...

Abstract

The invention relates to an additive which is a composition of nanometer powder body containing boron nitride, molybdenum and copper, wherein the powder body is a nanometer spherical solid particle formed by the boron nitride and molybdenum in covalent bond structure and the copper in coordination bond structure; the boron nitride is used as a spherical skeleton which the molybdenum covers in lamellar-structure, and the copper is combined at a crystal defect position of the sphere in the point and lamellar-structure. The solid particle is a compound nanometer particle of BN.Mo.Cu molecule. A preparation method comprises the steps of hydrolyzing borate and deionizing water in a high speed stirring mixer; respectively adding sodium nitride and diamide hydrate, heating; then adding coupling agent, ethanol, ammonium molybdate and copper sulfate one after another, forming complex salt alcosol; aging and forming in a high pressure reaction kettle; pressing the gel by using a high-pressure pump into an aerogel mixing generator, sintering a gasified complex salt aerogel product in a high temperature furnace, obtaining a nanometer ceramic metal compound particle; removing the water and adding adjustment solvent of liquid stearic acid, styrolized polyester and calcium petroleum sulfonate, then forming the composition of the nanometer powder body containing the boron nitride, molybdenum and copper.

Description

[0001] Technical field: The present invention relates to a nanoscale ceramic-metal composite additive for lubricating oil and grease and a preparation method thereof, belonging to ceramic-metal composite additives. Background technique: [0002] Nanotechnology is a high-tech emerging at the end of the 20th century. At present, nanotechnology has achieved rapid development in material science and mechanics, especially in the field of friction and lubrication. As lubricating oil additives, nanomaterials have been recognized at home and abroad in recent years for their excellent functions such as wear resistance, wear reduction, and mechanical load improvement. [0003] However, in the current market, there are only unit metal and binary metal nanomaterials, as well as unit and binary ceramic nanomaterials; due to the single performance of the unit body, the ideal effect cannot be achieved in use, while pure metal base and pure The effect of using ceramic base is not ideal.
